摘要: 采用溶液混合法制备了聚[(双-甘氨酸乙酯)膦腈](PGP)与丙交酯均聚物(PLA)或丙交酯/乙交酯共聚物(PLGA)的共混体系,利用示差扫描量热仪、傅里叶红外光谱仪和相差显微镜研究了两体系的共混相容性.实验结果表明,PGP与PLA不相容,但通过氢键相互作用可与PLGA达到部分相容,且PGP/PLGA的共混相容性随着PLGA含量的增加而有所改善.

Abstract: Poly[bis(glycine ethyl ester)phosphazene] was blended with poly(d,l-lactide)(PLA) or poly(d,l-lactide-co-glycolide)(PLGA) in various mass fraction ratios by using solvent-mixing technique. The miscibility of these blends was studied by DSC, IRand contrast microscopy method. The results showed that PGPwas completely incompatible with PLA, but partially compatible with PLGAdue to the hydrogen bonding effect. Furthermore, the miscibility of PGP/PLGAwas improved with the increase of PLGAcontent in the blend.

Key words: Polyphosphazene, Polyester, Polymer blend, Miscibility
